itself was pushing the city's population north and leaving Chambers Street behind. The Nassau Street Loop was completed in 1931 south to the Montague Street Tunnel to Brooklyn, making the Chambers Street BMT station a through station. At this point, the BMT's center island platform and the two side platforms were closed. A new northern mezzanine was built in 1938 when the entrances under the north side of the Municipal Building were closed. The western side platform was demolished with the expansion of the IRT station between 1960 and 1962. The Chrystie Street Connection, opened in 1967, severed the Nassau Street Line's connection to the Manhattan Bridge, so that the bridge tracks could connect instead to the uptown IND Sixth Avenue Line. The new connection preserved Nassau Street service via the Montague Street Tunnel, but trains were no longer able to run in a loop. The Chambers Street station, having fallen into disuse over the years, was voted the ugliest station in the system in a 2003 poll. In May 2018, it was announced that the MTA would start renovating the Chambers Street station that August. At the time, local news station NY1 said: "It is easily one of the most decrepit stations in the city's entire system." The station received two platform elevators and three new ramps in the mezzanine: one in the corridor between the IRT and BMT stations, and one from the BMT mezzanine to each platform elevators. The station platforms were modified to reduce the gap between trains and the platform edges, and a pedestrian bridge was installed above the tracks, connecting both of the open platforms. To accommodate the ramps, elevators, and pedestrian bridge, portions of the station and mezzanine were removed or reconfigured. These improvements made the station compliant with the Americans with Disabilities Act of 1990, and were funded as part of the 2015–2019 MTA Capital Program. The project was to take at least 24 months to be completed. A contract for the elevators' construction was awarded in August 2018, and the elevators opened by September 1, 2020. Station layout Just below street level, there are two overpasses above the IRT platforms, one at the center of the station and another near the south end. There is also an underpass at the extreme north end of the station. The underpass and northern overpass date from the 1962 renovation while the southern overpass is
